Add wiffi integration (#30784)

* Add integration for wiffi devices wiffi devices are DIY board manufactured by stall.biz. Several devices are available, e.g. a weather station (weatherman), an indoor environmental sensor (wiffi-wz) and some more. This intgration has been developed using a weatherman device, but should also work for other devices from stall.biz. * Fix pylint warning * Use WIFFI / STALL WIFFI instead of wiffi to be consistent with stall.biz * Don't update disabled entities. * fix complains - move wiffi specific code to pypi - remove yaml configuration code * incorporate various suggestions from code review * fix remaining comments from Martin * fix comments * add tests for config flow * fix comments * add missing requirements for tests * fix pylint warnings * fix comments * fix comments remove debug log rename .translations to translations * rebase and adapt to latest dev branch * Update homeassistant/components/wiffi/config_flow.py Co-Authored-By: Martin Hjelmare <marhje52@gmail.com> * Update homeassistant/components/wiffi/config_flow.py Co-Authored-By: Martin Hjelmare <marhje52@gmail.com> * fix missing import Co-authored-by: Martin Hjelmare <marhje52@gmail.com>
